'''Cosmology''' is the study of the structure and evolution of the [[universe]].

'''Cosmology''' is the study of the structure and formation of the [[universe]].

Ancient and [[medieval]] cosmologists were common, usually oriented around a world view of a stationary, [[flat earth]] as the center of the universe.  [[Aristarchus]] understood that the [[earth]] was spherical and circled the [[sun]].  With the increasing sophistication of observing techniques and equipment, a more modern understanding of the universe emerged.

Modern cosmological theories take into account [[Einstein]]'s [[Theory of Relativity]] and the recession of [[galaxies]] shown by [[Red Shift]]. Today the [[Big Bang theory]] is the theory that receives the most notice in scientific circles, but the [[Steady State theory]] is still advocated as well. [[Theological]] issues often play a role in questions of the past of the universe and how it came into being.  Whether [[God]] is in the equation of not severly changes the possibilities.

Much of modern cosmology is [[atheism|atheistic]],<ref>http://www.atheists.org/flash.line/atheism1.htm</ref> which rejects [[God]] as explanations for the existence of the universe. Instead it uses theories such as [[Counterexamples to Relativity|relativity]] and the [[Big Bang theory]] based on the recession of [[galaxies]] shown by [[Red Shift]]. [[atheism|Atheistic]] cosmology occurs in a [[Counterexamples to an Old Earth|time frame]] which predates that suggested by creation scientists of approximately 6000 years. Some [[Secular Science|secular scientists]] also advocate the [[Steady state theory]], though this is very small in comparison. Some also suggest a cyclic universe of expansion followed by contraction, repeating to infinity. This approach has no need for a supernatural creator ([[God]]) and avoids the problem of [[creation]]. A small number believe that the [[universe]] is in fact a highly advanced computer simulation.
